An exactly solvable model of wave-mean field interaction in integrable turbulence
T. Congy, G. A. El, M. A. Hoefer
The kinetic theory of soliton gases (SG) is used to develop a solvable model for wave-mean field interaction in integrable turbulence. The waves are stochastic soliton ensembles th…
Solitary wave-mean flow interaction in strongly nonlineardispersive shallow water waves
Thibault Congy, Gennady El, Sergey Gavrilyuk +2
The interaction of a solitary wave and a slowly varying mean background or flow for the Serre-Green-Naghdi (SGN) equations is studied using Whitham modulation theory. The exact for…
Breaking a superfluid harmonic dam: Observation and theory of Riemann invariants and accelerating sonic horizons
Shashwat Sharan, Judith Gonzalez Sorribes, Patrick Sprenger +4
An experimental and theoretical study of sonic horizons emerging from the dam-break problem in a Bose-Einstein condensate confined in an anisotropic harmonic trap is presented. Mea…
Mach reflection and expansion of two-dimensional dispersive shock waves
Gino Biondini, Alexander Bivolcic, Mark A. Hoefer
The oblique collisions and dynamical interference patterns of two-dimensional dispersive shock waves are studied numerically and analytically via the temporal dynamics induced by w…
Hydrodynamics of a Discrete Conservation Law
Patrick Sprenger, Christopher Chong, Emmanuel Okyere +3
The Riemann problem for the discrete conservation law is classified using Whitham modulation theory, a quasi-continuum approximation, and…
Whitham modulation theory and two-phase instabilities for generalized nonlinear Schrödinger equations with full dispersion
Patrick Sprenger, Mark A. Hoefer, Boaz Ilan
The generalized nonlinear Schrödinger equation with full dispersion (FDNLS) is considered in the semiclassical regime. The Whitham modulation equations are obtained for the FDNLS e…
